Lollipop Chainsaw trailer introduces Juliet's bodiless boyfriend Nick

If you've seen footage of Lollipop Chainsaw, you're probably wondering why there's a decapitated head hanging at Juliet's hip. Who or what is that thing? Well, we finally have an answer to that mystery: it's Nick Carlyle, Juliet's boyfriend.

After Nick was bitten by a zombie, Juliet performed some "emergency surgery" on-the-spot to save Nick's life. Despite being only a head, Nick does help out Juliet in some situations.

Lollipop Chainsaw will be released later this year for Xbox 360 and PlayStation 3.
